This paper presents a lab-on-a-chip for electronic manipulation and detection of
microorganisms based on the use of closed dielectrophoretic (DEP) cages combined with
impedance sensing. A prototype has been realized using a standard printed circuit board
(PCB) technology by which polystyrene microbeads have been trapped, concentrated and
quantitated, in agreement with CAD simulations, without the need for external optical
components. The experiment was successfully repeated with S. cerevisiae. The approach is …
